docs/cgroup-v1/blkio: update for 5.x kernels

2021-06-16T17:32:03Z

Commit bf382fb0bcef4 ("block: remove legacy IO schedulers", Oct 12 2018) removes the CFQ scheduler, together with blkio.weight and blkio.weight_device described in cgroup v1 documentation. Users are supposed to use the BFQ scheduler, which cgroup file for setting weight is blkio.bfq.weight, but there is no way to set per-device weight. Later, commit 795fe54c2a8 per-device weights for BFQ, meaning that blkio.bfq.weight and blkio.bfq.weight_device can be used in a way similar to the old CFQ cgroup interface. Yet, the cgroup v1 docs were never updated. Fix this: - use the new file names; - fix the range for weight (used to be 10..1000, now 1..1000); - link to BFQ scheduler docs.
